Boy did Linkedin and Reid Hoffman ever mess up with last fall’s big anti-spam move. Apparently millions of Linkediners have now lost their ability to post and carry on conversations as a result. So what happened? Well the geniuses at Linkedin decided to introduce a new feature to fight spam. The feature allows any group moderator to tag a user as a spammer and block them from posting again. However, what happens now is that the user isthen blocked from posting in any of his or her 50 groups. Before last fall, moderators only had the ability to block a user from their own group. Now it’s global.

Why on Earth did the History Channel Invite Carly Fiorina to Appear on The Men Who Built America Series?
